Research methods and the influence of oil residues on the properties of building bitumen

The composition and characteristics of the components used to obtain a new composition of the roofing bitumen composition. Methods for studying the bitumen composition after adding oil sludge, phenolic extract and spent bleaching clay are presented. Micrographs of 10% solutions of oil sludge and phenolic extract in toluene were obtained, as well as optical micrographs of solutions of spent bleaching clay and oil residue in toluene. The results of the composition and properties of BN 90/10 bitumen with individual components of the oil residue were obtained. Characterization of relaxation processes in the investigated compositions. Basic properties of bitumen compositions modified with oil residues.
